Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Chimney Company in Altadena, CA
Chimney repair in Altadena starts with understanding what these foothill homes actually need. Most of the houses we work on were built between the 1910s and 1950s, and their original brick or stone chimneys have spent decades absorbing canyon wind, wildfire smoke, and damp winter air. Sherwood Chimney Sweep handles the full span of chimney work in Altadena, from the annual sweep that keeps creosote in check to structural repairs on clay-tile flues and crumbling mortar joints. Call (833) 589-8498 when you need someone who understands older masonry, local wildfire codes, and why a cracked crown up here is not a cosmetic problem.
Why Altadena Homes Are Different
Altadena sits at the base of the San Gabriel Mountains, and the chimney work here reflects that geography. Summer brings hot, dry conditions that bake mortar and widen hairline cracks. Winter drops the temperature enough that damp air condenses inside flues, mixing with creosote to form an acidic paste that eats at clay tiles and brick. Then there’s the wind. Canyon gusts coming off the Angeles National Forest send branches, embers, and debris straight at chimney caps, and we routinely find caps bent or missing entirely on homes along the upper foothill streets. Wildfire smoke settles into chimneys as fine ash that bonds with creosote, creating a residue that is harder to remove than typical fireplace soot and smells acrid when the first fire of the season warms it up.
The housing stock compounds all of it. These are Craftsman bungalows and mid-century ranch houses with original masonry, shallow fireboxes, and clay-tile flues that were never designed for the way we use fireplaces now. Some have been retrofitted with inserts or pellet stoves, which changes the clearances and the liner requirements. When Sherwood Chimney Sweep evaluates a chimney in Altadena, we are looking at how the original 1940s flue is holding up inside a house that now has a modern appliance attached to it. That is not a generic inspection. It is specific to this town.
Styles & brands we work with
Our Main Altadena Services
Two services dominate the calls we get from Altadena homeowners: the annual chimney sweep and dryer vent cleaning. Both are fire-prevention work, and both get neglected for the same reason, which is that they are out of sight.
Chimney Sweep in Altadena
An annual chimney sweep in Altadena is the single most effective thing a homeowner can do to prevent a chimney fire. We remove creosote, inspect the flue lining, and flag the early signs of water intrusion or mortar failure before they become four-figure repairs. Local conditions, especially wildfire ash and the damp-winter creosote problem, make this a more urgent annual job in Altadena than in flat, dry neighborhoods. For a full walkthrough of what the sweep includes up here, see our dedicated page on Chimney Sweep in Altadena.
Dryer Vent Cleaning in Altadena
Lint-clogged dryer vents are the leading cause of household dryer fires, and Altadena’s older homes are particularly vulnerable because the vent runs are long, convoluted, and often original to the house. A vent that has never been cleaned is a blocked vent. We clean the full run from dryer to exterior termination, check the cap for wind damage and pest intrusion, and treat the work as part of the same fire-prevention program as the chimney. Read more on the Dryer Vent Cleaning in Altadena page.

Chimney Repair in Altadena
Altadena’s chimneys take a beating that newer homes in flatter neighborhoods never experience. The freeze-thaw cycle in winter, months of 90-degree heat in summer, and the occasional ember storm during wildfire season all work against masonry that has been standing since the Roosevelt administration. When a homeowner here calls about a chimney problem, it is rarely one issue in isolation. A cracked crown lets water into the mortar bed, which spalls the brick, which loosens the flashing, which lets more water in. Sherwood Chimney Sweep repairs the entire system, not just the symptom, and we carry the professional-grade materials, DuraFlex liner systems and HeatShield resurfacing, that the job requires. For the broader scope of this work, see Chimney Repair.
Chimney Cap Installation
Signs you need it
You hear birds or raccoons inside the chimney, you find rust flakes or metal pieces on the hearth, or a sweep shows signs of water damage at the top of the flue.
What it costs in Altadena
Chimney cap installation in Altadena typically falls between $175 and $370, depending on the cap size, material, and how accessible the crown is on your roof.
How we do it
We take the flue measurements, match a cap to the existing tile or liner, secure it to the crown with mechanical fasteners if the masonry allows, and seal the connection against water entry.
Chimney Cap Replacement
Signs you need it
The existing cap is missing, warped, sooted up from a small flue fire, or chewed through by a determined squirrel or raccoon.
What it costs in Altadena
Replacement runs $175 to $370 for the cap itself, but if the mounting crown is damaged, expect the work to overlap with crown repair, which adds to the total.
How we do it
We remove the old cap, inspect the crown and flue tile underneath, and install a replacement sized to maintain proper draft while keeping out animals, debris, and embers during wildfire events.
Chimney Liner Installation
Signs you need it
A camera inspection shows cracked clay tiles, missing mortar joints between tile sections, or a liner that has separated so badly it can no longer contain combustion gases.
What it costs in Altadena
Full liner installation in Altadena ranges from $950 to $2,750, though HeatShield resurfacing can often restore a liner for $400 to $1,100 when the damage is confined to surface deterioration.
How we do it
We run a camera through the existing flue to document the condition, then either resurface with HeatShield ceramic sealant or install a DuraFlex stainless liner matched to your appliance and fuel type.
Chimney Flashing Repair
Signs you need it
You see water staining on the ceiling near the chimney, damp brick around the roofline, or rusted metal where the chimney meets the roof.
What it costs in Altadena
Flashing repair in Altadena typically runs $150 to $500 depending on whether we are patching a small section or pulling and replacing the full saddle and step flashing.
How we do it
We remove the failed flashing, assess the roof-to-chimney junction, and install new galvanized or stainless flashing sealed with a high-temperature silicone that holds through Altadena’s winter rain and summer heat.
Chimney Crown Repair
Signs you need it
The concrete or mortar crown at the top of the chimney is cracked, spalling, or letting water run down the flue and into the masonry below.
What it costs in Altadena
Chimney crown repair in Altadena ranges from $175 to $450, assuming the crown can be resurfaced rather than fully rebuilt.
How we do it
We clean out the cracks, fill them with a flexible waterproof sealant, and resurface the crown with a slight slope so water sheds away from the flue instead of pooling.

Do I really need chimney repair, or can I wait?
That depends on the water. If moisture is getting past the crown, flashing, or liner, the damage compounds every winter in Altadena, and a $300 repair becomes a $2,000 rebuild. We show you camera footage of the actual condition so you can decide, and we will tell you plainly when work can wait a season.
Can you repair my chimney the same week I call?
Most chimney repairs in Altadena are scheduled within a few days, provided the parts are standard. Specialized liner kits may take a few days to order, and we will always quote you the timeline before we start the job.

What Altadena Customers Say

— Jodi Parker"Level two inspection before we bought the house. The report was detailed enough to use as a negotiating point and he explained every photo in it."
— Ruben Flores"Thorough sweep and a clear report. He was running late from the job before and arrived near the end of the window, though he did call to warn me."
